Abstract (en)
[origin: WO9107949A1] Delayed release compositions comprising an active compound and amorphus amylose and having an outer coating comprising a film forming cellulose or acrylic polymer material, for example glassy amylose are of particular value for the selective release of medicaments and diagnostic agents into the colon.
